However, exemplary embodiments are not limited thereto.

FIG. 1 is a conceptual diagram illustrating a system for providing objects used to access a service, according to an exemplary embodiment.

Referring to FIG. 1, the system includes at least one device 1000, a server 2000, and at least one service provider 3000.

The device 1000 provides context information associated with service utilization of the device 1000, to the server 2000. For example, the context information may include context items, such as, the type of service, a user who used the service, the type of a device that used the service, service usage time, a location where the service is used, another user who also used the service, and an application executed by the device. The device 1000 receives an object for accessing a recommended service according to circumstances of the device 1000, from the server 2000. The device 1000 may use a service provided by the service provider 3000, using the object based on a user input to the object. The context information denotes information about a service which the device 1000 uses and a situation in which the device 1000 uses the service. The device 1000 may be a smart phone, a mobile phone, a personal digital assistant (PDA), a lap top, a media player, a global positioning system (GPS) device, and other mobile or non-mobile computing devices. The device 1000 may also be a device that is wearable by users. For example, the device 1000 may be a watch, glasses, a hair band, or a ring each having a communication function and a data processing function. However, exemplary embodiments are not limited thereto, and the device 1000 may be any kind of apparatus capable of receiving an object from the server 2000 via a network and executing the object.

The server 2000 may recommend predetermined context items according to the types of services based on the context information received from the device 100, and may sell the recommended context items to the service provider 3000. The server 2000 may provide an object for accessing a service provided by the service provider 3000, to the device 1000, and may calculate a fee which is to be charged to the service provider 3000 when the device 1000 uses the object to access the service provided by the service provider 3000.

The server 2000 receives the context information associated with the service utilization of the device 1000 from the device 1000 and models the context information. The server 2000 may recommend at least one context item for each service type. The server 2000 may generate context models by matching recommended context items with service types. For example, the server 2000 may recommend context items, such as, ‘weekday mornings,’ housewife; and ‘TV,’ for a morning drama broadcasting service.

In response to a purchase request from the service provider 300 to purchase a context model, the server 2000 may sell the requested context model to the service provider 3000. Purchasing a context model may include purchasing all or some of the context items included in the context model. The server 2000 may match a requested context item with a service provided by the service provider 3000. The server 2000 may also provide a template for object generation and an editing tool to the service provider 3000, receive a template edited by the service provider 3000 from the service provider 3000, and generate an object that is to be provided to the device 1000 using the template.

The server 2000 may provide an object associated with a service provided by the service provider 3000, to the device 1000, and may calculate a fee which is to be charged to the service provider 3000 when the device 1000 uses the object to access the service provided by the service provider 3000, according to a charging method. The charging method may be determined when the service provider 3000 purchases a context item, but exemplary embodiments are not limited thereto.

The service provider 3000 transmits a purchase request for the context model recommended by the server 2000 to the server 2000. The service provider 3000 may be a device or a server. The service provider 3000 may purchase all or some of the context items included in a context model recommended by the server 2000 and associated with a service that the service provider 3000 itself provides. When the service provider 3000 purchases a context item, the service provider 3000 may provide a service to the device 1000, if the device 1000 is in a situation the same as or similar a situation corresponding to the purchased context item. For example, the service provider 3000 may purchase context items, such as, ‘weekday mornings,’ ‘housewife,’ and ‘TV,’ for a morning drama A that the service provider 3000 itself provides. In this case, when a housewife uses the TV on weekday mornings, the morning drama A may be provided to the TV being watched by the housewife.

The service provider 3000 may receive a template that is used in the generation of an object via which a service provided by the service provider 3000 can be provided, from the server 2000. The service provider 3000 may edit the received template by inserting information about a service provided by the service provider 3000 into the received template. The service provider 3000 may provide the edited template to the server 2000.

FIG. 2 is a flowchart illustrating a method in which the system of FIG. 1 provides a service to the device 1000 and determines a fee that is to be charged to the service provider 3000 when the device 1000 uses the service.

In operation S200, the server 2000 receives context information from a second device 1000-2. In operation S205, the server 2000 receives context information from a first device 1000-1. The context information is information about a service which the device 1000 uses and a situation in which the device 1000 uses the service. The device 1000 may use various types of services in various situations, and context information about the situations in which the device 1000 utilizes the services may be collected by the server 2000. Context items are details included in the context information. For example, the context items may include a user who used a service, the type of a device that used the service, service usage time, a location where the service is used, another user who also used the service, and an application executed by the device; however, exemplary embodiments are not limited thereto.

The context information may include all kinds of information about situations related to the user (or device) and a computing circumstance. For example, the context information may include all kinds of information capable of characterizing the situations about an environment, object, and state of the user (or device). The context information may be abstracted by the server 2000 and may be classified into several types according to the degree of abstraction.

The context information may include sensor data collected from a sensor included in the device 1000, data about an application program operated in the device 1000 by a user input, and data associated with a cloud server that the device 1000 used.

As illustrated in FIG. 21, the collected data may include, for example, streaming information, event information, and web service (cloud computing) information.

The streaming information is information that is collected in real time. For example, the streaming information may include sensor data that is collected from the device 1000 in real time. The event information is information that is generated in accordance with generated events. For example, the event information may include data about changes to settings of the device 1000. The web service information is information about the utilization of a web service of the device 1000, and may include information about various contents that the device 1000 uses by accessing various web resources (for example, a cloud server). The web service information may include an enormous amount of information provided by web resources, and accordingly may be updated according to a cloud computing method.

In operation S210, the server 2000 models the context information to create a context model. The server 2000 may model the context information by selecting context items according to the types of services. For example, the server 2000 may select at least one of a user who used a service, the type of a device that used the service, service usage time, a location where the service is used, another user who also used the service, and an application executed by the device, for the service. For example, if a housewife frequently watches a morning drama via the TV on weekday mornings, the server 2000 may select context items, such as, ‘weekday mornings,’ ‘housewife,’ and ‘TV,’ for a morning drama broadcasting service.

The server 2000 may match the selected context items with the types of services. For example, the server 2000 may create a context model by matching the context items ‘weekday mornings,’ ‘housewife,’ and ‘TV’ with the morning drama broadcasting service. The context model may be used when the service provider 3000 determines a context item which is to be matched with a service provided by the service provider 3000.

In operation S210, the server 2000 may model the context information. The server may create a context model from the context information using a context engine (not shown). The server 2000 may create a context model by inferring the collected context information via various methods. For example, the server 2000 may create the context mode using at least one of an ontology-based method and a probability-based method.

The server 2000 may store the context information as dynamic information and static information. At least a portion of the context information may be abstracted according to a certain rule. The context information may include, for example, concrete context information, basis context information, and abstract context information. The concrete context information is unprocessed data, and may be data that is collected via a sensor or application program installed within the device 1000 or via a cloud server. The concrete context information may include, for example, the latitude/longitude of a GPS, and a WiFi ssid. Information included in the table of FIG. 21 may be the concrete context information. The basis context information may be information which is identified as statistical data that is created by collecting concrete context information for a certain period of time. The abstract context information is information obtained from the concrete context information and the basis context information. The abstract context information may be dependent upon a domain. Further, the server 2000 infers the abstract context information based on context information. For example, “Samsung Coex Mall” is identified as a location of the device 1000 based on a GPS value (37.511238, 127.059602) and it is determined that the identified location is similar to a location listed in a user's event schedule. And it is determined that a standstill state of the device 1000 is maintained for a predetermined period of time due to an analysis of the GPS and accelerometer of the device 1000. And a Bluetooth ID of a participant's device registered in the event schedule of the user may be recognized.

The server 2000 may identify a context item and match the context item with a predetermined service, using the concrete context information, the basis context information, and the abstract context information, thereby generating the context model.

In operation S215, the service provider 3000 may transmit a purchase request for the context item to the server 2000. The service provider 3000 may receive information about the context model from the server 2000 and may determine, based on the information about the context model, a context item that is to be matched with a service provided by the service provider 3000. The service provider 3000 may select all of the context items included in a context model by selecting the context model. Alternatively, the service provider 3000 may select some of the context items included in the context model. The service provider 3000 may provide the ID of the selected context item or the ID of the context model to the server 2000, and may transmit a purchase request for the selected context item to the server 2000. While transmitting a purchase request for the determined context item to the server 2000, the service provider 3000 may provide the server 2000 with information about a charging method. The charging method may include, for example, an auction method, a group purchasing method, an exclusive purchasing method, a charging method according to the exposure degree of an object, and a charging method according to the utilization of services via an object; but exemplary embodiments are not limited thereto.

In operation S220, the server 2000 matches the service of the service provider 3000 with the context item. The server 2000 matches the service of the service provider 3000 with the context item purchased by the service provider 3000. The server 2000 may confirm that the service provider 3000 purchases the context item selected by the service provider 3000, and may match the context item selected by the service provider 3000 with the service of the service provider 3000. For example, the server 2000 may match ‘providing the morning drama A,’ which is the service provided by the service provider 3000, with the context items ‘weekday mornings,’ ‘housewife,’ and ‘TV.’

In operation S225, the server 2000 determines a charging method for the service provider 3000. The server 2000 may determine the charging method for the service provider 3000, based on the information about charging methods provided by the service provider 3000

For example, when the service provider 3000 requests to purchase context items A, B, and C of a service A via an auction method, the server 2000 may compare a bid amount submitted by the service provider 3000 against a bid amount submitted by another service provider (not shown) that has also requested to purchase the same context items A, B, and C of the service A via the auction method. When the bid amount submitted by the service provider 3000 is higher than the bid amount submitted by the other service provider, the server 2000 may determine that the service provider 3000 is charged according to the bid amount proposed by the service provider 3000.

For example, when the service provider 3000 requests to purchase the context items A, B, and C of the service A via a group purchasing method, the server 2000 may compare a bid amount submitted by the service provider 3000 with a bid amount submitted by another service provider (not shown) that has also requested to purchase the same context items A, B, and C of the service A via the group purchasing method. The server 2000 may determine the probabilities that an object for accessing a service of the service provider 3000 and an object for accessing a service of the other service provider would be exposed to users, based on the bid amount submitted by the service provider 3000 and the bid amount submitted by the other service provider. The server 2000 may determine how to charge the service provider 3000, based on exposure rate of the object for accessing the service of the service provider 3000 and a purchase fee proposed by the service provider 3000.

In operation S230, the server 2000 generates an object for accessing the service of the service provider 3000. The object denotes a user interface used to use the service of the service provider 3000. The object may include at least one piece of link information for receiving a service from the service provider 3000.

The server 2000 may provide the service provider 3000 with a pre-set template used to generate an object, and may receive a template edited by the service provider 3000 from the service provider 3000.

In this case, the server 2000 may provide an editing tool for editing a template to the service provider 3000, and the service provider 3000 may insert service information associated with a service provided by the service provider 3000 into the template using the editing tool. The service information is information associated with the service provided by the service provider 3000, and may include, for example, the title of the service, a link address for downloading content associated with the service, and an image associated with the service; however exemplary embodiments are not limited thereto.

The server 2000 may generate an object for accessing the service provided by the service provider 3000, using the edited template received from the service provider 3000. The server 2000 may also insert information about a reason why the object for accessing a service provided by the service provider 3000 is recommended to the device 1000, into the object. The server 2000 may generate the object by combining the template received from the service provider 3000 and a template received from at least one other service provider (not shown). However, when the service provider 3000 purchases a context item using an exclusive purchasing method, the server 2000 may insert the template of the service provider 3000, and not that of the other service provider (not shown), into the object.

The server 2000 may match the generated object with the context item purchased by the service provider 3000.

In operation S235, the server 2000 determines a current situation regarding the device 1000. The server 2000 may determine the current situation regarding the device 1000 by monitoring, for example, a user of the device 1000, the type of the device 1000, the location of the device 1000, a current time, a day of the week, and an application that is being performed by the device 1000.

In operation S240, the server 2000 provides the generated object to the first device 1000-1. The server 2000 may compare a situation corresponding to the context item purchased by the service provider 3000 with the current situation of the device 1000 and may provide the object to the device 1000 based on a result of the comparison. When the situation corresponding to the context item purchased by the service provider 3000 is the same as or similar to the current situation of the first device 1000-1, the server 2000 may provide the object for accessing the service of the service provider 3000 to the first device 1000-1.

FIG. 3 is a flowchart illustrating a method in which the server 2000 models context information, according to an exemplary embodiment.

In operation S300, the server 2000 receives context information from the second device 1000-2. In operation S305, the server 2000 receives context information from the first device 1000-1. The context information denotes information about a service which the device 1000 uses and a situation in which the device 1000 uses the service. The device 1000 may use various types of services in various situations, and context information about the situations in which the device 1000 utilizes the services may be collected by the server 2000. Context items denote details included in the context information. For example, the context items may include a user who used a service, the type of a device that used the service, service usage time, a location where the service is used, another user who also used the service, and an application executed by the device; however, exemplary embodiments are not limited thereto.

In operation S310, the server 2000 selects context items according to the types of services, based on the context information. The server 2000 may evaluate a situation where a service is used a preset number of times or more, and may select at least one context item based on the situation. For example, the server 2000 may recommend at least one of a user who used a service, the type of a device that used the service, service usage time, a location where the service is used, another user who also used the service, and an application executed by the device, as the context item of the service. For example, when housewives watch a morning drama via the TV on weekday mornings a preset number of times or more, the server 2000 may recommend context items ‘weekday mornings,’ ‘housewife,’ and ‘TV,’ as the context items of a morning drama broadcasting service. For example, when a user is in a school and shares pictures being taken in the school with his or her friends a preset number of times or more, the server 2000 may recommend context items ‘school,’ ‘friend,’ and ‘the present,’ as the context items of a picture sharing service. For example, when workers use taxis around their houses on weekday mornings a preset number of times or more often, the server 2000 may recommend context items ‘weekday mornings,’ ‘worker,’ and ‘around house,’ as the context items of a taxi recommending service.

In operation S315, the server 2000 may create context models by matching the selected context items with service types. The server 2000 may create a context model by matching at least one of the selected context items with a service type.

For example, the server 2000 may create a context model by matching at least one of the context items ‘weekday mornings,’ ‘housewife,’ and ‘TV’ with the morning drama broadcasting service. For example, the server 2000 may create a context model by matching at least one of the context items ‘school,’ friend; and ‘the present’ with the picture sharing service. For example, the server 2000 may create a context model by matching at least one of the context items ‘weekday mornings,’ ‘worker,’ and ‘around house’ with the taxi recommending service.

Information about the created context model may be provided to the service provider 3000, and the service provider 3000 may use the context model in order to determine a context item that is to be matched with a service provided by the service provider 3000.

The context item associated with the location of a user may include, for example, ‘anywhere’ and ‘school.’ The context item associated with the relationship between a user and a sharer may include, for example, ‘friend.’ The context item associated with the content-generated location may include, for example, ‘around a user’ and ‘school.’ The context item associated with the content-generated time may include, for example, ‘the past’ and ‘the present.’

The types of services associated with content sharing may include, for example, ‘message sharing’ and ‘picture sharing.’

The server 2000 may evaluate a situation where each service is used a preset number of times or more, and may recommend a context item as the context item of each service. For example, the server 2000 may recommend the context items ‘anywhere,’ ‘friend,’ ‘around a user,’ and “the past”, as the context items of a message sharing service. For example, the server 2000 may recommend the context items ‘school,’ ‘friend,’ ‘school,’ and “the present”, as the context items of a picture sharing service.

For example, the server 2000 may create a context model 5 by matching at least one of the context items ‘anywhere,’ ‘friend,’ ‘around a user,’ and “the past” with the message sharing service. For example, the server 2000 may create a context model 6 by matching at least one of the context items ‘school,’ ‘friend,’ ‘school,’ and ‘the present’ with the picture sharing service.

FIG. 6 is a block diagram illustrating context models created in relation to a taxi recommending service, according to an exemplary embodiment.

Referring to FIG. 6, context items may include context items associated with service usage time, context items associated with users who use services, and context items associated with service-used locations (ex: locations where the services are to be used). The context items associated with service usage time may include, for example, ‘weekday mornings’ and ‘Friday night.’ The context items associated with the users who use services may include, for example, ‘woman’ and ‘worker.’ The context item associated with the service-used locations may include, for example, ‘Gangnam station’ and ‘around the house.’

The server 2000 may evaluate a situation where the taxi recommending service is used a preset number of times or more, and may recommend a context item for the taxi recommending service. For example, the server 2000 may recommend the context items ‘Friday night,’ ‘woman,’ and ‘Gangnam station,’ for the taxi recommending service. For example, the server 2000 may recommend the context items ‘weekday mornings,’ ‘worker,’ and ‘around the house,’ for the taxi recommending service.

For example, the server 2000 may create a context model 7 by matching at least one of the context items ‘Friday night,’ ‘woman,’ and ‘Gangnam station’ with the taxi recommending service. For example, the server 2000 may create a context model 8 by matching at least one of the context items ‘weekday mornings,’ ‘worker,’ and ‘around the house’ with the taxi recommending service.

FIG. 7 is a flowchart illustrating a method in which the service provider 3000 purchases a context item, according to an exemplary embodiment.

In operation S700, the server 2000 provides information about a context model to the service provider 3000. The information about a context model may include information about matching of a service type with a context item selected by the server 2000. The server 2000 may identify a context model associated with a service provided by the service provider 3000, and may provide information about the identified context model to the service provider 3000. For example, when a service provided by the service provider 3000 is a broadcasting service, the server 2000 may provide at least one of a context model associated with the morning drama broadcasting service, a context model associated with the comedy show broadcasting service, a context model associated with the English lecture broadcasting service, and a context model associated with the baseball broadcast broadcasting service to the service provider 3000.

In operation S705, the service provider 3000 may select a context item based on the context model. The service provider 3000 may select all of the context items included in a context model by selecting the context model. Alternatively, the service provider 3000 may select some of the context items included in the context model.

The service provider 3000 may select at least one of the services that are provided by the service provider 3000, and may select a context item for the selected service. For example, when a morning drama broadcasting service is matched with the context items ‘weekday mornings,’ ‘housewife, and ‘TV’ in the context model, the service provider 3000 may select a morning drama A from among the services that are provided by the service provider 3000 and may select the context items ‘weekday mornings,’ ‘housewife,’ and ‘TV’ as the context items of the morning drama A.

In operation S710, the service provider 3000 provides an ID of the selected service and the selected context item to the server 2000. The service provider 3000 may transmit a purchase request for the context item selected for the selected service to the server 2000. For example, when the service provider 3000 selects the morning drama A and selects the context items ‘weekday mornings,’ ‘housewife,’ and ‘TV’ for the selected morning drama A, the service provider 3000 may provide the context items ‘morning drama A,’ ‘morning in weekdays,’ ‘housewife,’ and ‘TV’ to the server 2000. The service provider 3000 may transmit a purchase request for the context items ‘morning drama A,’ ‘morning in weekdays,’ ‘housewife,’ and ‘TV’ to the server 2000.

The service provider 3000 may provide information about the charging method related to and the fee charged for the selected context item, to the server 2000. Based on the context item purchased by the service provider 3000, the service provided by the service provider 3000 is provided to the device 1000, and thus the server 2000 may charge the service provider 3000 a predetermined fee. In this case, the server 2000 may determine a fee that is to be charged to the service provider 3000, based on the charging method and fee provided by the service provider 3000. The charging method may include, for example, an auction method, a group purchasing method, an exclusive purchasing method, a charging method according to the exposure degree of an object, and a charging method according to service utilization via the object; however, exemplary embodiments are not limited thereto.

In operation S720, the server 2000 matches the service provided by the service provider 3000 with the context item purchased by the service provider 3000. The server 2000 may confirm that the service provider 3000 purchases the context item selected by the service provider 3000, and may match the context item selected by the service provider 3000 with the service selected by the service provider 3000. For example, when the service provider 300 selects an auction method as a purchasing method and a bid amount submitted by the service provider 3000 is higher than that of another service provider, the server 2000 may finally determine to sell a context item to the service provider 3000. For example, the server 2000 may match the morning drama A of the service provider 3000 with the context items ‘weekday mornings,’ ‘housewife,’ and ‘TV.’

When the service provider 300 selects a group purchasing method as the purchasing method, the server 2000 may match the service provided by the service provider 3000 with the context item purchased by the service provider 3000 and the probability of exposure of the service provided by the service provider 3000.
